Increased risk of developing a sexually transmitted infection

Explanation:

Drug abuse typically means that the person would most likely be under influence, and therefore cannot think properly during that set duration.

Unprotected sex typically means that there is no protection at all from STDs if one or both of the partners have STDs currently.

Different partners means that there is a higher chance of obtaining STDs from one or more of the partners.

Therefore, your answer should be increased risk of developing a STD.
